Our society has become more dependent on software-intensive systems, such as Information and Communication Technologies (ICTs) systems, to perform their daily tasks (sometimes critical). However, in most cases, organizations and particularly small ones place limited value on information and its security. In the same time, achieving security in such systems is a difficult task because of the increasing complexity and connectivity in ICT development. In addition, security has impacts on many attributes such as openness, safety and usability. Thus, security becomes a very important aspect that should be considered in early phases of development. In this work, we propose an approach in order to secure ICT software architectures during their dev...
